7 Points You Must Know Of The High-speed Aluminum Blister Packaging Machine

1.The High Speed Development Of High-speed Aluminum Blister Packaging Machine

High-speed aluminum blister packaging machine is a new form of packaging for solid pharmaceuticals.

After first blistering and moulding the transparent plastic hard sheet, the tablets, pills, capsules and other solid drugs are filled in the grooves and then heated and bonded together with the aluminium box sheet coated with adhesive to form an independent sealed package.

At present, many domestic solid drugs are still packaged in glass bottles, which are protected from light, moisture and oxidation, but have a large packaging capacity and low technological content.

For the high requirements of special drugs, this traditional form of packaging will not be able to effectively prevent drug dampness and mildew, which is an important reason why the large-capacity brown glass bottle packaging is being rapidly withdrawn from the market in recent years.

Compared with bottled drugs, blister packaging is easy to carry, can reduce the pollution caused by drugs in the process of carrying and taking, that is, blister packaging has obvious advantages in the gas barrier, moisture permeability, health and safety, production efficiency, dosage accuracy and extend the shelf life of drugs .

The good barrier properties of blister packs are due to the choice of the raw material aluminium foil and plastic rigid sheets. The aluminium box has a highly dense metallic crystal structure with good barrier and light-shielding properties, while the plastic rigid sheet must have sufficient barrier properties against oxygen, carbon dioxide and water vapour, high transparency and non-cracking mechanical strength.

Currently, the most common pharmaceutical blister packaging materials are PVC sheet and PVDC (polyvinylidene chloride).

4.High-speed Aluminum Blister Packaging Machine Blister Forming Principle

High-speed blister packaging machine blister forming is an important process of the entire packaging process, blister forming methods can be divided into the following four types:

A.blister forming (negative pressure forming)

The use of vacuum to heat the softened film into the molding mold blister nest, forming a certain shape, to complete the blister molding. The blister is generally formed by using a roller mould, the scale of the blister is small, the shape is simple, the blister is unevenly stretched and the top is thin.

B.Blow molding (positive pressure molding)

Using compressed air to blow the heated and softened film into the blister nest of the molding mold, forming the desired shape of the blister. Blow moulding is mostly used for plate moulds, the wall thickness of the moulded blister is more uniform, the shape is straight, and a larger scale blister can be formed.

C.Punch assisted blow moulding

With the help of the punch, the heated and softened film is pressed into the mould cavity, and when the punch is fully pressed in, compressed air is introduced to make the film stick to the inner wall of the mould cavity, completing the forming process.

Punch-assisted forming is mostly used for flat blister packaging, which can be used to obtain uniform, large scale and messy blister shapes after reasonable planning.

D.Convex and concave die cold stamping forming

When the rigidity of the selected packaging material is larger (such as composite aluminum), the thermal forming method is obviously not applicable, but the use of convex and concave die cold stamping forming method, that is, the convex and concave die together, the film forming process, in which the air is discharged from the exhaust holes in the molding die.

5.How To Operate High-speed Aluminum Blister Packaging Machine

The specific correct sequence of operation of the high-speed blister packaging machine is as follows.

(a) You must often check the quality of the appearance of finished aluminium and plastic products, machine operation, if there are abnormalities immediately stop to check, normal before production.

(b)The to be sealed drugs, packaging materials are well prepared, replace the batch number word template, install the PVC and aluminum foil, check the cooling water, carefully clean the equipment.

(c)When the predetermined temperature is reached, press the start switch, the main machine turns clockwise and the PVC goes around the PVC heating roller, the filling hopper, the aluminium foil heating roller, the tensioning wheel, the batch number device and the punching and cutting mould in turn.

(d)Food machinery safety and health design process, safety aspects of the design, the first need to take direct safety measures to eliminate the possible dangers of food production, to ensure that food machinery safety production with a high degree of safety

(e)Turn on the power supply and connect the compressed air.

(f)Press the heating button and set the heating and heat sealing temperature control gauges to the appropriate temperature respectively.

(g)From the point of view of indicative safety measures and additional precautions to make up for the shortcomings brought about by direct safety measures, thus ensuring that the safe and hygienic design of the food machinery meets the actual production needs and avoids the presence of dangerous factors.

(h)Pull the PVC hard sheet through the channel under the punching knife and the aluminium foil under the heat sealing plate.

(i)Set the cooling temperature gauge to the right temperature when the heating and heat sealing plates are brought up to the right temperature (which should normally be 30°C).
